POSITAL closed-loop motor feedback for absolute positioning

By Lisa Eitel | July 2, 2018

Share

POSITAL FRABA encoders for closed-loop motor feedback allow upgrades to existing motion control applications. The mechanical drop-in replacement encoders have the same footprints as US Digital’s E5 models and Broadcom’s (Avago) HEDS-5500 models.

POSITAL kit encoders provide absolute position feedback — to give controls complete information on the physical position of the mechanical components they’re directing.

Many motion designs are designed around incremental encoders because incremental feedback devices were once less expensive than absolute encoders. But now POSITAL’s absolute kit encoders are comparable to those of incremental encoders, so design engineers must no longer make the choice based on cost.

• Identical assembly procedure to that of comparable encoders; no training required; diameters 4 to 10 mm (1/4 to 3/8 in.)

• Magnetic technology (to withstand harsher environments than optical encoders); improved connectivity via m12 connector additional available

Multiturn Absolute Kit Encoders from POSITAL are based on magnetic sensing technology. More specifically, the multiturn counting system is powered by Wiegand wire energy harvesting technology, which enables the absolute encoder to maintain true absolute position over power cycles and rotation of the encoder during power off conditions.

With 17 bits (131072 positions) of single turn resolution and 16 bits (65536 turns) of multiturn range, KCD Absolute kit encoders from POSITAL are ideal for position control applications.
